使用 webpack 构建 Npm 模块

const path = require("path");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const { CleanWebpackPlugin } = require("clean-webpack-plugin");

module.exports = {
  mode: "production",
  entry: {
    index: path.resolve(__dirname, "src/index.js"),
  },
  output: {
    filename: "[name].js",
    path: path.resolve(__dirname, "lib"),
    libraryTarget: "commonjs2"
  },
  devtool: "source-map",
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        use: ["babel-loader"],
      },
      {
        test: /\.(css|less)$/,
        use: [MiniCssExtractPlugin.loader, "css-loader", "less-loader"],
      },
      {
        test: /\.(png|svg|jpg)$/,
        use: ["file-loader"],
      },
    ],
  },
  plugins: [
    new MiniCssExtractPlugin({
      filename: "index.css",
    }),
    new CleanWebpackPlugin(),
  ],
  resolve: {
    alias: {
      "@": path.resolve(__dirname, "src"),
    },
    extensions: [".js", ".jsx"],
  },
  externals: /^(react|babel-runtime)/,
};
